I was using that tried & true method of taking a couple of small slow steps, click, then repeat, to get as close as I could to a western kingbird perched on the top of a dried out yucca stalk with no cover anywhere around in an open wildflower field. It is not easy to get close shots under these circumstances. With my first click, the bird turned and glared at me.
